Problems solved by technology

Corrugated cardboard often encounters extrusion during use. When the corrugated cardboard is squeezed, the burst resistance of the corrugated cardboard has a great influence on the extrusion resistance of the cardboard. , there will be obvious deformation, which will affect the use of corrugated paper
The strength of three-layer cardboard in conventional products is low, and it is easy to deform during use. The strength of conventional five-layer cardboard is slightly higher than that of three-layer cardboard. However, due to insufficient manufacturing density, the strength is not high, and the consumption cost is high, occupying space and Big size
In addition, corrugated cardboard may be wetted by rainwater and sea water during use, which will affect its use. Conventional three-layer cardboard and five-layer cardboard are not waterproof and moisture-proof, and generally penetrate within 5 minutes. Sizing is the best It does not exceed 10 minutes and cannot protect the packaged items well

Abstract

The invention discloses an impermeable four-layer composite corrugated board which is formed by surface paper, inner paper and two layers of core paper, wherein the two layers of core paper, as well as the core paper and the inner paper are adhered through an adhesive A; the two layers of core paper and the surface paper are adhered through an adhesive B; the adhesive A comprises the following components in parts by weight: 950-1050 parts of water, 280-290 parts of corn starch, 8-12 parts of sodium hydroxide, 2-3 parts of sodium borate and 55-58 parts of tannin; the adhesive B comprises the following components in parts by weight: 750-850 parts of water, 280-290 parts of corn starch, 8-12 parts of sodium hydroxide, 2.5-3.5 parts of sodium borate and 48-52 parts of tannin. According to the composite corrugated board, a glue layer is additionally arranged in the middle, so that the ring crush compression resistance of the composite corrugated board is obviously enhanced, and the strength is 5%-10% higher than that of a five-layer corrugated board quantified comprehensively. The corrugated board is impermeable within 90 minutes (preferably 15 hours), and can play a good role in protecting packaged goods.

Description

Technical field: [0001] The invention belongs to the technical field of packaging materials, and in particular relates to an anti-permeation high-strength composite corrugated cardboard. Background technique: [0002] Corrugated cardboard began at the end of the 18th century, and its application increased significantly in the early 19th century because of its light weight, low price, wide range of uses, easy production, and the ability to be recycled or even reused. By the beginning of the 20th century, it had been fully popularized, promoted and applied for the production of packaging for various commodities. Since the packaging container made of corrugated cardboard has its unique performance and advantages for beautifying and protecting the goods inside, it has achieved great success in the competition with various packaging materials, and has become a long-lasting and presentable product so far. One of the main materials for the rapid development of packaging containers...
